New USB Stack
TexasRockbox:
The "System" -> "Rockbox sytem" screen shows
1. "Charging" when plugged in and charging.
2. "100%" and time remaining when full
3. Just shows a remaining time when not charging
I have the Apple charger. Probably paid too much but it keeps everything all in the family.

Since the new USBStack (whatever that is...) is in place, I noticed that uploading music or firmware to my ipod nano is way slower when the rockbox-firmware is active than under apple-firmware. It is not like a USB1.1 to 2.0 comparison but well noticeable. I don't know whether or not it was that slow before, since I didn't notice the difference then.
I'm also experiencing difficulties connecting the device to my PC in order to let it recognize the ipod at all. It usually takes 4-7 attempts to connect the device until it boots up in disk mode allowing me to access it while charging. But sometimes it suddenly works by the first attempt (as it was the case before the USB Stack-upgrade). I couldn't find out what's special about those cases. I always guessed it could be the cable/connector but now I see it's a comon problem.
More suitable it would be, if connecting the ipod to the PC always makes the device accessible while a mode to "listen-while-charging" should activated by a pressed key (i.e. select) during plugging in.

Oppaunke, the new USB stack (what lets the iPod talk to the PC over a USB cable) is not complete - all it does currently, is request more power for charging. Whenever you were/are transferring files between your iPod and computer, you were/are using the Apple firmware.
The black-and-white screen with "do not disconnect" is Apple's "emergency disk mode" (accessible by rebooting the iPod with menu+select, and then straight away holding play+select). All Rockbox previously did, was reboot itself into this disk mode. The emergency disk mode is also slower than the normal disk mode in the Apple firmware.

Especially on Nanos. Reboot into the original firmware to get full speed transfer going.

Thank you, now everything makes sense to me - this means patience is due :-)
